HEADER 0R COUPLING.

Application led February 10, 1922. Serial No. 535,436.

My invention relates more particularly to headers or couplin meanswhereby the ends of a plurality of differently disposed tubes or pipesare connected together in fluid-t1ght y relation with each other, inorder that aI continuous flow of fluid through the respective. pipesections or tubes of a heater, still, boiler, or other tubularfluid-containing element may be conveniently and readily provided.

ne object vof my invention is to provide a construction whereby theadjacent ends of oppositely or dierently disposed tubes or pipes `maynot only be readily connected together in fluid-tight relation, butwhich also permits easy and* full access to be had to the interior ofthe connected tubes or pipes for cleaning; the header or coupling beingso formed and provided with openings dis posed in alignment withytherespective ends of the tubes or pipes.

'A further object of my inventionis to' provide a header wherein thelclosure mem- .bers and the openings in the header may be provided withground seats to produce Huidtight joints; while the header or coupling,

about the openings therein, is formed te en sure a proper seating of theclosure members; the invention also involving means whereby the closuremembers are firmly held in place by regulable' pressure-applying meanswhich may not only be quickly applied but also readily released topermit removal of the closure members.

he objects and advantages of m invention will be more readily comprehened from the detailed description of the accompanying drawing, whereinFigure 1 is a longitudinal sectional view of my improved header orcoupling as ap plied to the ends of two tubes or pipes, of which only aportion is shown.

Figure 2 is a vertical sectional view, taken substantially on the line 22 of Figure 1.

My improved header or coupling, while adapted to boilers and devicesemploying a series of tubes or pipes disposed in different directions,is more especiallyYV intended for use in connection with oil heatingapparatus or the oil'conveying tubes of furnaces and in the particularexempliication ofthe invention comprises a sultable header or hollowcasting 10, which in this 4instance is of rectangular configuration,with lone side wall 'thereof' apertured to receive the ends of the tubesor pipes 11, which are suitably secured -or ange 14. The outer surfaceof the' cap to the side which receives the respective tubesl l orpipe-ends and at points in direct align,l

. ment with the pipe-receiving openings, fis

provided ywith a corresponding number ofI openings as at 12. Theopenings 12 are prefs' erably all provided with a tapered or beveledseat as at 13 which terminates at the outer surface in a circumferentialrib orridge 14' disposed entirely about the orifice or opening 12.

l The side Wall of the header 10, which rel ceives the tubes or pipes11,\is preferably y provided with longitudinal ridges or ribs 15, 1 5lengthwise of the opposite longitudinal sides; and the inner, o posingfaces of the ribs preferably 'provide with a taper or bevel, as moreclearly shown in Figure 2. The ribs 15 are adapted toreceive the taperedbent ends or beveled hook portions 16 of a strap or yoke 17 which isadapted to straddle rthe header, as shown invFigure 2.

The orifice or opening 12 is adapted to receive a cap or-closuremember`18, which is preferably of the arcuate formation shown, while theperimeter thereof is, beveled to correspond with the taper or bevel ofthe I orifice 12 in the header 10, in order that the cap 18 may fit orcome -flush with the beveled seat 13 of the orifice 12. The cap 18 isalso preferably formed so that a portion of the perimeter ofthe cap orclosure member 18 is made to extend parallel with the flat or perendicular surface of the continuous rib or closure member 18 is shownprovided with a slight Socket or recess to receive the end of a screw orpressure-applying member 19 which extends through a tapped openingfinthe yoke or bracket member 17. parent from the construction shown, themembers or yokes 17 are slid lengthwise into place from the ends of theheader or coupling 10, with the-hooks or end portions 16 of the, bracketmember in engagement 105 with the inner faces of the longitudinal ribs15; the closure members or caps are then seated in place and thepressure-applying members or bolts 19 then screwed firmly into contactWiththe respective caps or closure 110 AS 1S ap- 100 members, therebsecurellocking the caps or closure mem ers 4in uid-tight relation withthe header 4or casting.

In return couplings or constructions as heretofore employed, screw-plu swere used to close the access openings an these plugs,

after the heater or still had been in use, became ummed or corroded,necessitating considera le'force and exertion to remove the plugs. Thecorrosion of the threads, as well as the frequent screwing of the Aplu sinto and out of place, has resulted in the t reads becoming torn orworn, which in frequent cases necessitated a replacement or renewal ofthe entire header or coupling, as well as resulting in seriousaccidents. With my invention, these dilliculties are entirel eliminated;the loss of time prevented an a pressure resisting construction isprovided.

In order that the caps or closure members may be easily removed andmanipulated, 1 prefer to provide the outer surfaces thereof with thetool-receiving sockets indicated at 20, which permit the use of asuitable Wrench or tool whereby to dislodge the cap or closure memberand at the same time facilitate the grinding of the caps or closuremembers in place.

With my improved construction, where the access openings are surroundedby the ribs or Ilan es 14, itis apparent that proper seating of t e capsor closure members is not only ensured, but any shifting or sidewisedisplacement of the closure members will be prevented; the ribs tendingto properl center the closure members or caps, there y ensuring theproper application of the pressure induced by the pressure-applyingmembers 19.

I have shown what I believe to be the simplest embodiment of myinvention, having described the same in terms employed merely as termsof description and not as terms of limitation, as structuralmodifications are possible and may be made without, however, departingfrom the spirit of my invention.

What I claim is A header of the character described, comprising a hollowrectangular body, one side whereof is provided With tube-receivingopenings while the opposite side is provide with openings aligned withthe tube-receiving openings, the second mentioned openings havingoutwardly ared conical surfaces of comparative width terminating inannular'l flan es disposed about said openings and exten ing upwardlyand parallel with the axes of the openings, closure members for thesecond mentioned openings, having inwardly and downwardly beveledperimeters corresponding in width with said conical ared surfaces andperpendicular cylindrical surfaces extending parallel with said flanges,yoke'members adapted to straddle the body and tobe disposed transverselyof and in spaced relation with the closure members, the

ends of the yoke members being bent inwardly and engaging with thetube-receiving side of the bod the yoke ends and body being formed wit 1coacting gripping surfaces, and regulable pressure means threadedthrough the intermediate portions of the yoke members and engaging withthe tops of the closure members. e
